Wyoming Spring Thaw Weight Restrictions (Frost Laws)

Wyoming Spring Thaw Weight Restrictions

Published on the statewide road-conditions map. Wyoming restricts fewer miles than its neighbours because much of the state system is built on free-draining base.

The source, and how we read it

Map viewer · Not machine-readablePolled weekly (off season)

Publisher: Wyoming Department of Transportation
Authoritative page: https://www.wyoroad.info/
Format: Map viewer — Not machine-readable
What we do with it: Watched for change and linked. We do not synthesise a limit from a map or a PDF.
Posting season: 02-01 to 05-15 — WYDOT posts seasonal load restrictions through its road-conditions system as districts thaw.
Polling cadence today: Outside Wyoming's posting window by 117 days — polled weekly, so an unscheduled restriction and a broken source are both found before the season opens.
If our copy goes stale: It errs toward showing a restriction the state has already lifted, because this source publishes only what is currently in force.
